1 U-Boot is Free Software. It is copyrighted by Wolfgang Denk and 2many others who contributed code (see the actual source code for 3details). You can redistribute U-Boot and/or modify it under the 4terms of version 2 of the GNU General Public License as published by 5the Free Software Foundation. Most of it can also be distributed, 6at your option, under any later version of the GNU General Public 7License -- see individual files for exceptions. 8 9 NOTE! This license does *not* cover the so-called "standalone" 10applications that use U-Boot services by means of the jump table 11provided by U-Boot exactly for this purpose - this is merely 12considered normal use of U-Boot, and does *not* fall under the 13heading of "derived work". 14 15 The header files "include/image.h" and "include/asm-*/u-boot.h" 16define interfaces to U-Boot. Including these (unmodified) header 17files in another file is considered normal use of U-Boot, and does 18*not* fall under the heading of "derived work". 19 20 Also note that the GPL below is copyrighted by the Free Software 21Foundation, but the instance of code that it refers to (the U-Boot 22source code) is copyrighted by me and others who actually wrote it. 23-- Wolfgang Denk 24 25======================================================================= 26 27 GNU GENERAL PUBLIC LICENSE 28 Version 2, June 1991 29 30 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 31 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA 32 Everyone is permitted to copy and distribute verbatim copies 33 of this license document, but changing it is not allowed. 34 35 Preamble 36 37 The licenses for most software are designed to take away your 38freedom to share and change it. By contrast, the GNU General Public 39License is intended to guarantee your freedom to share and change free 40software--to make sure the software is free for all its users. This 41General Public License applies to most of the Free Software 42Foundation's software and to any other program whose authors commit to 43using it. (Some other Free Software Foundation software is covered by 44the GNU Library General Public License instead.) You can apply it to 45your programs, too. 46 47 When we speak of free software, we are referring to freedom, not 48price. Our General Public Licenses are designed to make sure that you 49have the freedom to distribute copies of free software (and charge for 50this service if you wish), that you receive source code or can get it 51if you want it, that you can change the software or use pieces of it 52in new free programs; and that you know you can do these things. 53 54 To protect your rights, we need to make restrictions that forbid 55anyone to deny you these rights or to ask you to surrender the rights. 56These restrictions translate to certain responsibilities for you if you 57distribute copies of the software, or if you modify it. 58 59 For example, if you distribute copies of such a program, whether 60gratis or for a fee, you must give the recipients all the rights that 61you have. You must make sure that they, too, receive or can get the 62source code. And you must show them these terms so they know their 63rights. 64 65 We protect your rights with two steps: (1) copyright the software, and 66(2) offer you this license which gives you legal permission to copy, 67distribute and/or modify the software. 68 69 Also, for each author's protection and ours, we want to make certain 70that everyone understands that there is no warranty for this free 71software. If the software is modified by someone else and passed on, we 72want its recipients to know that what they have is not the original, so 73that any problems introduced by others will not reflect on the original 74authors' reputations. 75 76 Finally, any free program is threatened constantly by software 77patents. We wish to avoid the danger that redistributors of a free 78program will individually obtain patent licenses, in effect making the 79program proprietary. To prevent this, we have made it clear that any 80patent must be licensed for everyone's free use or not licensed at all. 81 82 The precise terms and conditions for copying, distribution and 83modification follow. 84 85 GNU GENERAL PUBLIC LICENSE 86 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 87 88 0. This License applies to any program or other work which contains 89a notice placed by the copyright holder saying it may be distributed 90under the terms of this General Public License. The "Program", below, 91refers to any such program or work, and a "work based on the Program" 92means either the Program or any derivative work under copyright law: 93that is to say, a work containing the Program or a portion of it, 94either verbatim or with modifications and/or translated into another 95language. (Hereinafter, translation is included without limitation in 96the term "modification".) Each licensee is addressed as "you". 97 98Activities other than copying, distribution and modification are not 99covered by this License; they are outside its scope. The act of 100running the Program is not restricted, and the output from the Program 101is covered only if its contents constitute a work based on the 102Program (independent of having been made by running the Program). 103Whether that is true depends on what the Program does. 104 105 1. You may copy and distribute verbatim copies of the Program's 106source code as you receive it, in any medium, provided that you 107conspicuously and appropriately publish on each copy an appropriate 108copyright notice and disclaimer of warranty; keep intact all the 109notices that refer to this License and to the absence of any warranty; 110and give any other recipients of the Program a copy of this License 111along with the Program. 112 113You may charge a fee for the physical act of transferring a copy, and 114you may at your option offer warranty protection in exchange for a fee. 115 116 2. You may modify your copy or copies of the Program or any portion 117of it, thus forming a work based on the Program, and copy and 118distribute such modifications or work under the terms of Section 1 119above, provided that you also meet all of these conditions: 120 121 a) You must cause the modified files to carry prominent notices 122 stating that you changed the files and the date of any change. 123 124 b) You must cause any work that you distribute or publish, that in 125 whole or in part contains or is derived from the Program or any 126 part thereof, to be licensed as a whole at no charge to all third 127 parties under the terms of this License. 128 129 c) If the modified program normally reads commands interactively 130 when run, you must cause it, when started running for such 131 interactive use in the most ordinary way, to print or display an 132 announcement including an appropriate copyright notice and a 133 notice that there is no warranty (or else, saying that you provide 134 a warranty) and that users may redistribute the program under 135 these conditions, and telling the user how to view a copy of this 136 License. (Exception: if the Program itself is interactive but 137 does not normally print such an announcement, your work based on 138 the Program is not required to print an announcement.) 139 140These requirements apply to the modified work as a whole. If 141identifiable sections of that work are not derived from the Program, 142and can be reasonably considered independent and separate works in 143themselves, then this License, and its terms, do not apply to those 144sections when you distribute them as separate works. But when you 145distribute the same sections as part of a whole which is a work based 146on the Program, the distribution of the whole must be on the terms of 147this License, whose permissions for other licensees extend to the 148entire whole, and thus to each and every part regardless of who wrote it. 149 150Thus, it is not the intent of this section to claim rights or contest 151your rights to work written entirely by you; rather, the intent is to 152exercise the right to control the distribution of derivative or 153collective works based on the Program. 154 155In addition, mere aggregation of another work not based on the Program 156with the Program (or with a work based on the Program) on a volume of 157a storage or distribution medium does not bring the other work under 158the scope of this License. 159 160 3. You may copy and distribute the Program (or a work based on it, 161under Section 2) in object code or executable form under the terms of 162Sections 1 and 2 above provided that you also do one of the following: 163 164 a) Accompany it with the complete corresponding machine-readable 165 source code, which must be distributed under the terms of Sections 166 1 and 2 above on a medium customarily used for software interchange; or, 167 168 b) Accompany it with a written offer, valid for at least three 169 years, to give any third party, for a charge no more than your 170 cost of physically performing source distribution, a complete 171 machine-readable copy of the corresponding source code, to be 172 distributed under the terms of Sections 1 and 2 above on a medium 173 customarily used for software interchange; or, 174 175 c) Accompany it with the information you received as to the offer 176 to distribute corresponding source code. (This alternative is 177 allowed only for noncommercial distribution and only if you 178 received the program in object code or executable form with such 179 an offer, in accord with Subsection b above.) 180 181The source code for a work means the preferred form of the work for 182making modifications to it. For an executable work, complete source 183code means all the source code for all modules it contains, plus any 184associated interface definition files, plus the scripts used to 185control compilation and installation of the executable. However, as a 186special exception, the source code distributed need not include 187anything that is normally distributed (in either source or binary 188form) with the major components (compiler, kernel, and so on) of the 189operating system on which the executable runs, unless that component 190itself accompanies the executable. 191 192If distribution of executable or object code is made by offering 193access to copy from a designated place, then offering equivalent 194access to copy the source code from the same place counts as 195distribution of the source code, even though third parties are not 196compelled to copy the source along with the object code. 197 198 4. You may not copy, modify, sublicense, or distribute the Program 199except as expressly provided under this License. Any attempt 200otherwise to copy, modify, sublicense or distribute the Program is 201void, and will automatically terminate your rights under this License. 202However, parties who have received copies, or rights, from you under 203this License will not have their licenses terminated so long as such 204parties remain in full compliance. 205 206 5. You are not required to accept this License, since you have not 207signed it. However, nothing else grants you permission to modify or 208distribute the Program or its derivative works. These actions are 209prohibited by law if you do not accept this License. Therefore, by 210modifying or distributing the Program (or any work based on the 211Program), you indicate your acceptance of this License to do so, and 212all its terms and conditions for copying, distributing or modifying 213the Program or works based on it. 214 215 6. Each time you redistribute the Program (or any work based on the 216Program), the recipient automatically receives a license from the 217original licensor to copy, distribute or modify the Program subject to 218these terms and conditions. You may not impose any further 219restrictions on the recipients' exercise of the rights granted herein. 220You are not responsible for enforcing compliance by third parties to 221this License. 222 223 7. If, as a consequence of a court judgment or allegation of patent 224infringement or for any other reason (not limited to patent issues), 225conditions are imposed on you (whether by court order, agreement or 226otherwise) that contradict the conditions of this License, they do not 227excuse you from the conditions of this License. If you cannot 228distribute so as to satisfy simultaneously your obligations under this 229License and any other pertinent obligations, then as a consequence you 230may not distribute the Program at all. For example, if a patent 231license would not permit royalty-free redistribution of the Program by 232all those who receive copies directly or indirectly through you, then 233the only way you could satisfy both it and this License would be to 234refrain entirely from distribution of the Program. 235 236If any portion of this section is held invalid or unenforceable under 237any particular circumstance, the balance of the section is intended to 238apply and the section as a whole is intended to apply in other 239circumstances. 240 241It is not the purpose of this section to induce you to infringe any 242patents or other property right claims or to contest validity of any 243such claims; this section has the sole purpose of protecting the 244integrity of the free software distribution system, which is 245implemented by public license practices. Many people have made 246generous contributions to the wide range of software distributed 247through that system in reliance on consistent application of that 248system; it is up to the author/donor to decide if he or she is willing 249to distribute software through any other system and a licensee cannot 250impose that choice. 251 252This section is intended to make thoroughly clear what is believed to 253be a consequence of the rest of this License. 254 255 8. If the distribution and/or use of the Program is restricted in 256certain countries either by patents or by copyrighted interfaces, the 257original copyright holder who places the Program under this License 258may add an explicit geographical distribution limitation excluding 259those countries, so that distribution is permitted only in or among 260countries not thus excluded. In such case, this License incorporates 261the limitation as if written in the body of this License. 262 263 9. The Free Software Foundation may publish revised and/or new versions 264of the General Public License from time to time. Such new versions will 265be similar in spirit to the present version, but may differ in detail to 266address new problems or concerns. 267 268Each version is given a distinguishing version number. If the Program 269specifies a version number of this License which applies to it and "any 270later version", you have the option of following the terms and conditions 271either of that version or of any later version published by the Free 272Software Foundation. If the Program does not specify a version number of 273this License, you may choose any version ever published by the Free Software 274Foundation. 275 276 10. If you wish to incorporate parts of the Program into other free 277programs whose distribution conditions are different, write to the author 278to ask for permission. For software which is copyrighted by the Free 279Software Foundation, write to the Free Software Foundation; we sometimes 280make exceptions for this. Our decision will be guided by the two goals 281of preserving the free status of all derivatives of our free software and 282of promoting the sharing and reuse of software generally. 283 284 NO WARRANTY 285 286 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY 287FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN 288OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES 289PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED 290OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF 291MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS 292TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE 293PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, 294REPAIR OR CORRECTION. 295 296 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 297WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 298REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 299INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING 300OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED 301TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY 302YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER 303PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE 304POSSIBILITY OF SUCH DAMAGES. 305 306 END OF TERMS AND CONDITIONS 307
